Samsung T7 Shield vs SanDisk Extreme comes down to one number first: the 1 TB SanDisk Extreme we link to reads up to 2,000 MB/s, the T7 Shield up to 1,050 MB/s. After that the two are close. Both makers list IP65 and a 3 meter drop, both list 256-bit AES encryption, and the warranties differ by two years. Here is the side-by-side, with each maker's own page as the source. Every number in this guide comes from the makers' own pages. Checked on 9 October 2026.
Quick answer
Most people: the SanDisk Extreme. On the makers' pages it is the faster drive (up to 2,000 MB/s read) and has the longer warranty (5 years, against 3). The Samsung T7 Shield prints its write speed (1,000 MB/s), weight (98 g) and size on its page, and is the smaller number on speed only. Check the price on Amazon before you choose, because it changes. Checked on 9 October 2026.

How we compared them
The NomadsToolsLab team read Samsung's and SanDisk's product pages end to end on 5 October 2026, checked both Amazon pages with a US address, and went back to the maker pages and the Amazon buy buttons on 9 October 2026 to see what had changed. What surprised us: Samsung's US page prints speed, IP65 and the drop rating but not the warranty, encryption or weight, so those come from its UK page and are marked that way, while SanDisk says its speed and drop figures come from its own internal testing.
Testers at ShutterMuse bought a T7 Shield and measured it with 256 MB and 64 GB files. Writes peaked around 1,100 MB/s and settled near 800 MB/s on big files, reads were more modest, and a nearly full drive made little difference. Against the earlier SanDisk Extreme (V2) the SanDisk hit higher peaks on small files, but the Samsung held its write speed better on large ones. That test is of the V2. The Extreme we link is the newer V3, which SanDisk rates up to 2,000 MB/s and which we did not find independently tested. Every number in the table comes from the makers' own pages.

SanDisk Extreme: Not on the page
Sources: Samsung's US page and UK page (the UK page lists encryption, warranty and weight), and SanDisk's Extreme page (model SDSSDE70-1T00-G25). Speeds are "up to": SanDisk says its figure is based on internal testing and depends on the host device, and the IP65 and drop figures are internal tests too. SanDisk adds that the drive must be clean and dry before use.
Samsung T7 Shield: the numbers it prints
Samsung T7 Shield Portable SSD 1 TB
Samsung lists the T7 Shield with USB 3.2 Gen 2 (10 Gbps), read and write of up to 1,050 and 1,000 MB/s, IP65 and a 3 meter drop rating. Its UK page adds AES 256-bit hardware encryption, a size of 59 x 88 x 13 mm and a 3-year limited warranty, and names the Samsung Magician software for managing the drive. It also comes in 2 TB and 4 TB.
SanDisk Extreme: faster, with 5 years
SanDisk Extreme Portable SSD 1 TB
SanDisk's page lists the Extreme (V3) in 500 GB, 1 TB, 2 TB and 4 TB, with up to 2,000 MB/s read, IP65, up to 3 meter drop protection, password protection with built-in 256-bit AES encryption and a 5-year limited warranty. The encryption needs a software download, and works on Windows 10 and later and macOS 12 and later, says SanDisk.
One thing to check: there is more than one SanDisk Extreme. Older listings carry other model numbers and other speeds. The drive we link is the 1 TB model SDSSDE70-1T00-G25, so compare that number on the page before you buy.
